References to cluster rules

[Ben_01880]

When using a references to a cluster are there limitations

when it is passed to a sub vi ?

   Can the cluster contain other clusters ?

   Can a "type def" cluster contain "strict type def" clusters?

   Can references go stale ?

   Can you reference a reference ?

   I create arrays of references, are there any issues ?

   Can references go stale ?  Possibly.  Depends on the type of reference.  If it is the kind of reference to something that you can open, and later close it, any further use of that reference would be stale.

   Can you reference a reference ?  I don't think so, but I don't know.  I've never had a situation where I thought I needed to do it.  What is your use case?

   I create arrays of references, are there any issues ?  As long as each element in the array is of the same type of reference.  So if you had a reference to a numeric arrayed with a boolean, the resulting array will be coerced to their nearest common class which would be just a control reference (as opposed to a boolean control reference, or a digital numeric control reference.)
